Summary
Ayumi Saito is a frontend developer with a decade of professional experience who specializes in React and TypeScript, with deep expertise building UX-focused interfaces for FinTech products. At Billie she helped migrate projects to a monorepo, authored a TypeScript-based design system, and reinforced quality with Cypress integration tests—skills that bridge product design and robust engineering. Her background in sales and international trading gives her a rare commercial perspective on user flows and onboarding, especially for B2B payments and merchant experiences. Based in Chiyoda, Japan, and connected to Berlin’s frontend community, she pairs practical frontend craftsmanship with a data-minded approach to product decisions. Ayumi’s training from freeCodeCamp and Udacity complements her Waseda social science degree, making her equally comfortable translating business needs into polished, testable UI components. Colleagues describe her as a collaborative problem-solver who brings cross-cultural negotiation experience to distributed engineering teams.
